What cube root equals 686? In other words, what number would you take the cube root of to get 686? To solve this problem, we want to find x in the following equation:
∛x = 686
To solve the ∛x = 686 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 686³
x = 686³
Then, we calculate 686³ to get the following answer:
686³ = 686 × 686 × 686
686³ = 322,828,856
∛322,828,856 = 686
We made the equation above so you will get a full understanding of how to solve problems like this. In the future, note that you can solve all similar problems by simply multiplying the number by itself twice to get the answer.
